303.04.0021.05 Repair Kit for ECAS Solenoid Valves

What is an ECAS solenoid valve repair kit?

An ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system. The kit typically includes essential components such as O-rings, gaskets, diaphragms, the plunger, and the spring. By replacing these internal elements, the valve block can effectively fill and vent air bellows based on control unit commands to maintain constant chassis height.

Vehicle compatibility and engine fitment

This repair solution is widely used for Volvo, Renault Trucks, Ford Trucks, and Mack trucks. It is also fitted to MAN, Scania, Mercedes-Benz, and various other heavy commercial vehicle brands. Specifically, it serves models such as Volvo FH13, Renault Trucks Premium, and Ford Trucks Cargo series to ensure optimal suspension performance.

Maintenance and installation guidance

For workshop technicians, using a repair kit instead of replacing the entire valve block provides a cost-effective maintenance solution. When installing, ensure all sealing elements are seated correctly to prevent air leaks or delayed level response. Proper maintenance helps avoid vehicle sagging while parked.

Troubleshooting suspension stability

Regular inspection of the solenoid valve components can prevent unexpected downtime in fleet operations. If you notice uneven chassis height or slow air response, consult your authorized distributor.
